Yes, that's correct. The "ST3320620A" above is the disk model (seagate st
etc), the second word I guess it is a serial number.
If that worries you, then use labels instead - but in that case, you can
mount two partitions with the same label in order to copy data from one to
the other.

Depends on what your procedure is.
The label is dependent on the formated filesystem, it is saved somewhere
there. If a partition is badly hosed, the label is lost: I know because it
happened to me.
The disk ID is more resistant, and it is usable in the cryptotab file
(label mounting doesn't work there).
